AC magnetic contactor的用法和样例：
- Hyperthermia therapy with AC magnetic field heating magnetic nanoparticles is a new kind of treatment method.
- When the DC magnetic field is maintained at a fixed value,there is a good linearity between the output signal and the AC magnetic field which is below 1 kA/m.
- The AC magnetic permeabilities of stainless steel rod and amorphous ribbon are measured by the method and the result is in accordance with other reported values.
- AC magnetic field induction heating device is the key device of tumor thermotherapy, which is the most difficult monitoring and controlling middle and high frequency strong magnetic field.
